MAX1179AEUI+T

Analog To Digital Converters (ADC) Overview

The MAX1179AEUI+T is a 16-bit successive-approximation analog-to-digital converter (ADC) featuring a bipolar ±5V analog input range. It operates from a single +4.75V to +5.25V analog supply and interfaces with digital logic ranging from +2.7V to +5.25V. The device provides a 16-bit wide parallel interface and supports a maximum sampling rate of 135ksps. Key performance metrics include a maximum integral nonlinearity (INL) of ±2LSB and differential nonlinearity (DNL) of ±1LSB. Power consumption is 23mW at 135ksps using an external reference, or 29mW with the internal +4.096V reference. The AutoShutdown mode reduces current to 0.4mA at 10ksps.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm that the AEUI designation corresponds to the extended temperature range (-40°C to +85°C). Ensure compatibility with existing board layouts regarding the 28-pin TSSOP footprint and pin configuration before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX1179 variant specifically for its ±5V input range capability. Consider the MAX1187 or MAX1189 if unipolar 0-10V or wider bipolar ±10V ranges are required instead. Evaluate the need for the internal reference versus an external precision reference based on system noise requirements and board space constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1179/MAX1187/MAX1189 family of 16-bit, low-power ADCs manufactured by Analog Devices / Maxim Integrated. These devices share common architectural features such as SAR conversion techniques and parallel interfaces, differing primarily in their analog input voltage ranges and specific package temperature ratings.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include the MAX1179ACUI+ for commercial temperature ranges or the MAX1179BCUI+ for tighter linearity specifications. Verify pinout compatibility and software register configurations when substituting these variants.
